本文引入 Chen 等人 (2004) 所提出考慮斜坡底床坡度之勢能函數於演進型緩坡方程式 (EEMSE) 中求得斜坡底床修正參數後,再依據能量守恆處理方式將此參數加入演進型緩坡方程式,探討波浪傳遞斜坡底床因底床坡度效應造成波浪變形之影響。本文模式首先針對 Chen 等人 (2004) 之理論解析進行驗證,與 Chen 等人 (2004) 相同底床坡度條件下皆得到良好ㄧ致性。此外本文探討 Booij’s ramp (1983) 不同坡度底床地形及 歐 等人 (2007) 沙漣試驗造成反射波之反射率,結果顯示於適當坡度範圍內本文模式可呈現優於傳統緩坡方程式計算結果並與試驗結果相近。本文模式進而延伸探討波浪傳遞於不同坡度斜坡上佈置正弦形沙漣計算波浪反射率變化,結果指出於 EEMSE 中引入底床坡度效應可於適當坡度範圍內呈現與具底床擾變效應之緩坡方程式相同優異模擬能力。
The velocity potential proposed by Chen et al. (2004) is re-derived based on the energy conservation law and is incorporated in the Evolution Equation for Mild-Slope Equation (EEMSE, Hsu and Wen, 2001) for investigating wave deformation behaviors of regular waves propagating over a sloping bottom. The present model is capable of simulating bottom slope effect for waves propagating from deep to shallow water.
The model capability is reasonably validated against the theory of Chen et al. (2004). Additionally, the model is calibrated by simulating Booij’s ramp (1983) and the experiments of Ou et al. (2007). The comparisons show the present model are in agreement with available theories and experiments.
In particular, the model is further applied to investigate the wave reflection properties of regular waves propagating over sinusoidal topography on sloping beaches. The slope effect is studied. Comparisons show that wave reflection increases with the increase of ripple length. Overall, the simulated results exhibit that the present model is capable of simulating the reflection behaviors as well as the EEMSE.
